Hi Fellas
There are a few threads out there on the internet regarding Vikings that crank and don’t start due to fuel pump not coming on, or Vikings that are running then suddenly stop and will crank with full gauges but no fuel pump sound. I have thrown my 2cents at a couple to try and help. Fuses, starter solenoid relays, fuel pump, switches, subs, batteries, spark plugs etc etc. I have been having issues with this type of stuff on and off for a while now, because I plow water like a mad mofo submarine commander I thought maybe it is operator related. This is what I have just found, after I replaced the fuel pump and it still worked intermittently, hopefully it helps someone else in the Viking world.

Blue and yellow wire loose inside of connector. Pull the blue wire forward Viking fuel pump primes and starts, push the blue and yellow wire back - Viking dies in the ass and fuel pump will not run.
From the factory this plug has always been a tight fit with no extra wire and the wires that come out of the plug bend with a 90degree Cheers

That's a good find and good help. I had a 12 month old V8 Commodore that would die at the lights sitting idling, no fuel pump, had to get pushed off the road numerous times, eventually found the exact same thing as you, when they pushed the Deustch plug together at the factory one of the wires got half pushed back out of the plug, intermittent connection.

I wish i would have saw this before i pulled the tank and changed out a working pump. 5 minutes to change the fuses i missed or 2 hours to pull the tank and fuel pump. Dang it

Viking was cranking but not starting.. noticed a fuse blown. Put new battery in and replaced every fuse. After that viking started and idled for about 3-5 seconds then died. Tried to restart and did not hear fuel pump. The same fuse blew again. Replaced it and same occurrence with fuse blowing 3-5 seconds and again and again.

Was hoping someone has had a similar experience with some solutions. Next im pulling fuel pump to make sure its filter is not plugged.

Did this ever get fixed? I'm having similar issues

I had the FI fuse blowing for a while, it ended up being the wire that goes to the fuel injector was rubbing under the cross brace that runs on top of the chassis under the tray. Worth a look. Cheers
